Android - 单击时菜单项崩溃（相机意图）

Question

I have a menu item that uses a camera intent. But whenever it is clicked, it crashes. I tested it with several different methods of camera intents, and they all caused crashes. The code is in the link below (as StackOverflow was acting strange when I try to directly insert Java code)

MainActivity/CameraIntent: https://gist.github.com/VirusThePanda/2c99048977c16f7e1ffa

LogCat: https://gist.github.com/VirusThePanda/66a13a58674fdacea224

Menu:

 <item
        android:id="@+id/photo"
        android:icon="@drawable/ic_photo"
        android:title="Take Photo"
        android:onClick="phototake"
        app:showAsAction="ifRoom" />

Please note that the MainActivity and Menu is not the full file. Just the important parts for this question.

Answer 1

Your error log shows you have SecurityException: Permission Denial...with revoked permission android.permission.CAMERA. This means you are targetting API level 23 and the user has revoked the CAMERA permission. You should add code to check and request permission and handle permission acceptance/denial.
